    • An illuminating device includes a light guide plate; a light source that is located opposite at least two adjacent end faces of four end faces of the light guide plate; and a chassis that has an opening through which light emanating from a light emission surface of the light guide plate passes. At least one optical sheet that includes a corner portion with an interior angle of greater than 90 degrees in a position corresponding to a corner portion of the light guide plate that is sandwiched between the two end faces opposite the light source is disposed between the light emission surface of the light guide plate and the chassis.
    • 照明装置包括导光板; 光源,其与所述导光板的四个端面的至少两个相邻的端面相对; 以及具有从导光板的发光面发出的光通过的开口的底架。 至少一个光学片包括在对应于导光板的夹在与光源相对的两个端面之间的导光板的角部的位置处具有大于90度的内角的角部, 导光板和底盘的表面。

    • There is provided a color conversion method. The method includes: a black correction step of converting the first black corresponding to the first color data having a tone value of 0 to the second black corresponding to the second color data having a tone value of 0 so that when the first black corresponding to the first color data having a tone value other than 0 is converted to a value smaller than a quantization threshold of tone values 0 and 1 of the second color data, a conversion destination becomes greater than or equal to the quantization threshold; a recording agent limit quantity calculating step of setting an upper limit of the sum of tone values for each pixel of the second color data with respect to a predetermined print medium; and a chromatic color correcting step of converting the second chromatic color so that the second color data after conversion in the black correction step does not exceed the upper limit.
    • 提供了一种颜色转换方法。 该方法包括:黑色校正步骤,将具有音调值0的第一颜色数据对应的第一黑色转换为与色调值为0的第二颜色数据相对应的第二黑色,使得当对应于 将具有0以外的色调值的第一颜色数据转换为小于第二颜色数据的色调值0和1的量化阈值的值,转换目标变为大于或等于量化阈值; 记录剂限制量计算步骤,用于相对于预定打印介质设置所述第二颜色数据的每个像素的色调值之和的上限; 以及彩色校正步骤,用于转换第二色彩,使得黑色校正步骤中的转换后的第二颜色数据不超过上限。
